Zusammenfassung:	To provide a radio wave absorber having a wide frequency bandwidth showing high reflection attenuation in a frequency band including 76 GHz to 81 GHz.SOLUTION: A radio wave absorber 1 includes a base material 10 and a radio wave absorbing film 20 formed on the base material 10. The radio wave absorbing film 20 contains at least MTC type ε-FeOand black titanium oxide. The MTC type ε-FeOis the same space group as the ε-FeOcrystal, and is represented by ε-MTiCoFeO(M is an element comprising at least one element selected from Ga, In, Al, and Rh, and 0
